Cell cycle arrest of Saccharomyces cerevisiae in G1 by the antimitogen alpha-factor is mediated by activation of a signal transduction pathway that results in inhibition of the cyclin-dependent kinase Cdc28-Cln. The Far1 protein is required for cell cycle arrest and associates with the Cdc28-Cln complex. The kinase activity of Cdc28-Cln was directly inhibited by Far1 both in vivo and in vitro, thus demonstrating that Far1 acts at the final step in the alpha-factor response pathway by inhibiting a G1 cyclin-dependent kinase.
SciCrunch is a data sharing and display platform. Anyone can create a custom portal where they can select searchable subsets of hundreds of data sources, brand their web pages and create their community. SciCrunch will push data updates automatically to all portals on a weekly basis. User communities can also add their own data to scicrunch, however this is not currently a free service.
